I'm not sure how useful getLoadedClasses would even be. Most classes load so late that you'd never see them in this list, and since the purpose of doing the import is to get access to classes you haven't accessed yet...they're almost certain to not be loaded. I guess I don't see a good solution other than the Jython packagecache, since in all cases the purpose of getting the list of classes is to discover classes we haven't loaded yet. There's simply no way for anything that depends on classes being loaded *first* to give us a useful list. - Charlie --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "JVM Languages" group.
